First focus of the multidisciplinary team of advisors was and is the analysis and - wherever required - the re-engineering of the relevant business processes in all operational activities related to the provision of efficient water supply and wastewater disposal services. Especially the workflows related to water production, transmission to distribution and the meter reading, billing and revenue collection had to be analysed, as they heavily contribute to the most critical and composite performance indicator of a water utility - the unaccounted for water (UFW) or non revenue water (NRW).
Prior to targeted action, the required base data and information must be available in reasonable quantity and quality. For this purpose, OMS designed, developed and introduced an integrated, GIS based information management system, which combines technical, operational, commercial and financial data for analysis and resulting remedial action.
Extensive base data surveys, like a house-to-house comprehensive subscriber survey (CSS) of 592,700 water subscribers took place, more than 2,000 km2 of cadastral maps and 12,000 km of pipe networks were digitised and converted into a structured geo database.
To introduce and maintain a high quality standard of workmanship and to enable the introduction of modern technologies, OMS supported WAJ in the establishment of a vocational training centre and the development of water sector related short term training courses. Further human resource development takes place in form of on-the-job training of staff and specialised training courses in information technology, GIS, organisational development and financial management.
